Adding mixed numbers {basic math}

Sheila ran 1  2/5 miles on Monday and 2  1/3 miles on Tuesday.  What was the total distance, in miles, Sheila ran during those two days?
A.)  3  2/15
B.)  3  3/8
C.)  3  2/5
D.)  3  7/15
E.)  3  11/15

Add the two distances,  1  2/15 and 2  1/3, together to find the total distance.

1  2/15  +  2  1/3
=  1  2/15  +  2  5/15   {got common denominator of 15, by multiplying numerator and denominator of 1/3 by 5}
= 3  7/15   {added 1 and 2, and also combined the numerators over the common denominator}

D.)  3  7/15
